4 claims. (01. 126-215) My inventionrelates to improvements in safetygas grates and it consists of the combinations, constructions andarrangements, hereinafter described and claimed.

An object of my invention is to provide a safety gas grate which may bequickly attached to a stove and positioned above a burner so as tosupport a receptacle and prevent the water from the receptacle droppingdown upon the 10 flame should the receptacle boil over. The meansactually contacting with the receptacle for supporting it provides aliquid-tight seal which prevents water flowing down the outside of thereceptacle from gravitating along the bottom of 16 r the receptacle andthen dropping upon the flame. The device employs grooves terminatingbeyond the circumference of the burner so that water dropping from theouter end of the grooves will not find its way down on the flame. Thedevice .!Lwill effectually protect the flame regardless of how violentthe overflow from the receptacle may be.

A further object of my invention is to provide a device of the typedescribed which is simple in gconstruction and which is durable andeflicient for the purposes intended.

Other objects and advantages will appear in the following specification,and the novel features of the device will be particularly pointed out in30 the appended claims.

My invention is illustrated in the accompanying drawing forming a partof this application, in which Figure 1 is a top plan view of my device;

,5? Figure 2 is a transverse section through the device; a

Figure 3 is a section along the line 3-3 of Figure 1; V I

Figure 4 is a perspective view of a portion of 9 I the device; and

Figure 5 shows a sectional view of a modified form of the device. 7

In carrying out my invention I make use of a gas grate indicatedgenerally at 1 (see Figures 1 451 and 2) and this grate has radiallyextending bars 2 projecting inwardly, these bars being slightly inclinedin the manner shown in Figure 2. It is obvious that the bars may behorizontally disposed if desired'without departing from the spirit 95..and scope of my invention.

My device comprises a ring-shaped member indicated generally at 3, thismember having an apron 4 and an annular flange 5 extending upwardlyfromthe'ap'ron and being. integral there- 5 Eiwith. The apron isprovided with a plurality of arch shaped members 6 which form grooves'7. (see Figure 2) for receiving portions of the bars 2. If desiredcement may be usedfor securingthe bars 2 to the apron rafter the barshave been disposed in the arch-shaped members. If the bars 2 areinclined as shown in Figure 2 the cement need not be used because anywater draining beneath the arches 7 will drop upon the bars 2 and beconveyed away from the burner 8 instead of toward the burner, due to theinclination of the bars. The purpose of the cement is to prevent thisdraining of the water along the bars 2 should they be disposed in ahorizontal position j which is' the general practice.

Between the arches 7 I dispose sighting grooves 9 formed in the underside of the apron 4. Portions of the apron 4 are bent in the mannershown in Figure 3 for forming the sighting grooves 9. When the device isplaced on the grate 1 the grooves 9 extend at an angle which permits theoperator to look at the flame without the necessity of stooping over sofar as when it is necessary to lower the eyes to the level of the bottomof the receptacle.

It is obvious that the sighting grooves 9 may be dispensed with ifdesired as shown in Figure 5 without departing from the spirit and scopeof my invention. r

A flexible ring 11, preferably of asbestos, is placed around the flange5 and is held in place by a split clamping ring 12. The ends of the ring12 have ears 13 and 14 with openings'and a bolt 15 is inserted throughthe openings and may be tightened for clamping the ring 12 about theflexible ring 11.

The flexible ring extends above the tops of the flange 5 and the ring 12and is preferably made of asbestos so as to be fire resisting.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

The receptacle 10 is placed upon the device so as to be supported by thering 11 as shown in Figure 2. The ring 11 will conform to the irregu-While I have shown only the preferred forms Y of my invention, it shouldbe understood that various changes or modifications may be made withinthe scope of the appended claims without g grate having an apron witharches for receiving departing from the spirit of the invention.

I claim: I

1. A safety gas grate comprising an outwardly extending apron, aflexible and non-inflammable member disposed about the ring, and a splitring clamping the member to the first ring, said member projecting abovethe rings.

"2. A safety gas grate comprising a ring having an outwardly extendingapron,a' flexible and non-inflammable member disposed about the a ringhaving,

ring, and a split ring clamping the member to the first ring, saidmember projecting above the rings, said apron having water conveyinggrooves therein.

3. The combination with a gas stove having bars, of a ring having anintegral apron with water grooves, said apron also having arches forreceiving the bars, and a flexible, non-inflammable member secured tothe ring and projecting above it; a i J 1. The combination withreceptacle supporting bars disposed above a burner, said bars beinginclined downwardly at a slight angle from a position above the centerof the burner, of a safety the barsand, having water conveying groovesin its upper surface, and a flexible, non-inflammable member disposedadjacent to the inner edge of "the apron and designed to support andform a water-tight seal withra receptacle for deflecting overflowingwater from the receptacle the apron.
